WI M wo s m QALQIFPBNJA- i se -wt ws es ta sma- The present invention relates to improvements in ii i ternal combustion engines and its particular object is to provide means in con nection with the commonly used internal combustion engine having a charge forming device for admitting fuel into' tliecombu stion chamber in a gaseous state for introducing liquid containing explosive materialinto the gaseous charge whereby the effectiveness of the combustion is increased. A further object or" the invention isto provide suitable means for controlling the supply of liquid into the charge. further object is to cause these control means to be governed by the exhaust gases of the engine in such a manner that when the engine is running slowly very little or no liquid is introduced while as the engine speeds up the liquid supply is increased. A'turther object is to provide suitable means preventing the liquid from flooding the charge forming device, the latter means being adapted at the saine time to admit a desired amount of air into the liquid. l v v i "With these objects in view I have illustrated the preferred form of my invention in the accompanying drawing inwhich Figure 1 shows a sideielevation of an internal combustionengine such asmight be used in a motor vehicle with my device attached thereto; Figure 2 is a sectional detail view of a valve operating mechanism along line 2-2 of Figure 1 and Figure? a sectional detail view of another valve taken along line 3-3 of Figure 1 While I have illustrated only the preferred form of my invention I wish to have'it understood that various changes or modifications may be made withinthe scope of the claims hereto attached without departing from the spirit of the invention.

The engine (1') shown in the drawing is of the ordinary type used for motor vehicles and is provided with a carburetor (2). an intake manifold (3) and an exhaust inanitold (4). A communicating pipe (6) connects the carburetor with the intake manifold and the throttle (7) is shown adjacent the carburetor. The latter receives its fuel such as gasoline from any suitable source not shown in the drawing, through the pipe (8). These detailsare well known in the art and the operation of this device is well. understood. The current of air is sucked past the gasoline in the carburetor by the intake strokes of the various pistons and carries gasoline v a or with it to form a proper for t e combustion clianiberf. The amount ortnar'ge admitted is regulated bythe throttle (7 Th i -s t he P es t n e t on is to introduce an additional element into the e;x- 'ploSive mixture fwhilch will" increase the "pawerof the' e'xplosion'. additidnal he"; ment is in liquid-form and may consist oft solution 'ofsaltpete'r, water and 'sul hur.

This liquid I store in the tank (9) which may beplaced underneath the front seat or in any other suitable position. A t,ube(11) leads" from this tank a; tlie commjunication (6)"be'tw eenthe intake and the carburetor preferably underneath the throttle (7) so that the supply of liquichwillbe subject to the throttle control in the same manner as the gasoline charge coming from the carburetor. I have from actual experience that the addition of this liquid to the gasone har e is ii e' esir b s wh h i gine is running at full speed'andleast desirable when the engine is running slowly. I

have thereforedeveloped a means which is ei ema i elly" ii ol e b hespe Of the engin for controlling the liquid supply in the desired manner. This 'in'eans is flingtrated in detail in Figu re 2 and comprises a valve (12) ,within the tube (11) and a control for this valve actuated by the exhaust.

gases of theengine. The valve (12) is conical shaped and fits in a conical seat, a perforation (13) in the valve being adapted to register with'the tube (11) in a certain position while closingsaid tube when turned through a quarter of a turn. The vertical valve stein (14) extends to within close proximity of the exhaust pipe (17) and is rotatably supported in the housing (16) covering a portion of the exhaust pipe, the lat ter being provided with an opening (18) allowing the vane (19) rigidly secured to the vertical stem (14) to extend into the exhaust pipe so as to be struck by the exhaust gases. Normally the valve (12) is in aposition where it closes the tube. The exhaust gases in striking the vane (19) tend to turn the valve stem into a position Where the perforation (13) registers with the tube (11) thereby opening the same. The tendency of the exhaust gases to open the valve is counteracted by suitable springs (21) tending to close the valve. In this manner the exhaust gases and the springs will cooperate in causing the vane (19) to oscillate, opening the valve for brief intervals when the oscillations are suiiiciently strong to cause the perforation in the valve to register with the tube. This is the case only when the machine is running at full speed or almost at full speed so that my liquid fuel is admitted into the charge only at that time and then in very small quantities. To convey an idea as to the quantity of liquid to be used I might state that I ordinarily use about one and onehalf pint of solution to a gallon of gasoline, without of course Wishing to limit myself to that amount.

In Figure 3 will be noticed a detail view of a second valve provided in the tube (11). This valve serves various purposes. A ball (23) is confined in an angular recess (2%) of a downwardly extending passage (26). Normally this valve will allow any liquid to pass through the same so as to prevent it from passing into the carburetor due to the bouncing of the ball on its seat through the effect of engine suction at slow speeds and vibration of the automobile. But when the running engine creates Suficient suction in the pipe (11) to draw the ball (23) toward the upper seat the opening (26) will be closed and liquid will pass the same. It is understood, of course. that this suction is pulsating and does not hold the ball against its seat continuously but allows the same to vibrate and allows air to pass through the valve during these vibrations, which air will be mixed with the passing liquid. This valve therefore acts in a similar manner the valve (12) and allows liquid to pass only when the engine is running suiiiciently fast to create a suction strong enough to hold the ball against its seat.

It will be noted from the foregoing description that the liquid containing the explosive is thus allowed to enter the comn'iunieatii'ig pipe (5) together with the gasoline charge from the carburetor and is drawn into the engine by the suction of the fuel. supply tank, a tube connecting the fuel supply tank with the intake pipe, a turnable valve v'itl1i n the tube for controlling the flow of fuel from the auxiliary fuel supply tank to the intake pipe, a valve stem extending outwardly from the valve, tensionable means connected to the valve stem for yieldingly holding the valve in closed position, and a vane extending laterally from the valve through the opening of the exhaust pipe and intothe path of movement of the exhaust gases and operable thereby to open the valve against the act-ion of the tensionahle means.

An internal combustion motor having an intake pipe and an exhaust pipe provided with a lateral opening, an auxiliary fuel supply tank, a tube connecting the auxiliary fuel supply tank with the intake pipe and havingan outwardly and downwardly extending air passage, a gravity operated vaive normally closing the said air passage and responsiveto the suction within the in take pipe to open the air passage whereby air is admitted into the tube, a turnable valve within the tube for controlling the flow of fuel from the auxiliary fuel supply tank to the intake pipe, a valve stem extending outwardly from the valve, tensionable means connected to the valve stem for yieldingly holding the valve in closed position, and a vane extending laterally from the valve through the opening of the exhaust pipe and into the path of movement of the exhaust gases and operable thereby to open the valve against the action of the turnable VILLIAH GGODFELLOW.
